Some Basic Definitions:
Radiation--The spreading of energy by electromagnetic waves.
Conduction--The transfer of heat by molecular motion from a source of high temperature to a region of lower temperature, tending toward a result of equalized temperatures.
Convection--The mechanical transfer of heated molecules of a gas or liquid from a source to another area, as when a room is warmed by the movement of air molecules heated by as radiator.
Molecules--The smallest particle of any compound that has the chemical properties of that compound. Materials are considered to be made of molecules held together by attractive forces.
Susceptor--A material, usually a thin, metalized film inside the packaging of microwave foods, which converts microwave energy into heat energy and promotes the browning of foods.
